F. W 000K. SAW MILL SET WORKS.
No. 410,349. Patented Sept. 3, 1889.
UNITED STATES PATENT CFFICE.
FREDERICK IV. COCK, OF FRANCISCO, CALIFORNIA.
SAW-MILL SET-WORKS.
SPECIFICATION forming part of Letters Patent No. 410,349, dated September 3, 1889.
Application filed April 24, 1889. Serial No. 308,438. (No model.)
To all whom it may concern.-
Be it known that I, FREDERICK W. 000K, of the city and county of San Francisco, State of California, have invented an Improvement in Saw-Mill Set-WVorks; and I hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to the class of sawmill set-works, and especially to the lever mechanism by which the set-works are operated; and my invention consists in the hereinafter-described novel mechanism for obtaining accuratefractional movements of the works.
The object of my invention is to provide a simple and effective means for readily and accurately limiting and defining the movement of the set-lever.
Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is aside elevation of my improvement. Fig. 2 is a plan of the same.
A is one of the sills or beams of the saw-mill carriage.
Bis the set-shaft,which extends on one side longitudinally of said carriage and communicates movement to the screws at each end, which operate the knees of the set-works, it being unnecessary herein to show said screws and knees.
Upon the set-shaft and suitably connected therewith and arranged in relation thereto is,
the mechanism represented by D, and which affects the movement of the set-shaft, the particular description and operation of said mechanism being unnecessary, as it forms no part of my invention.
E is the vibrating setlever which operates the mechanism D. Its lower end or foot is double or forked and extends up on each side of the set-bar F. This bar is pivoted at one end at the point f and has on its other end a handle portion f, provided with a spring-controlled pawl f*, the end of which is adapted to engage the curved rack G, which is fixed in position and is provided with a series of holes g. end the series of shoulders or stops f which are properly graduated, as shown. I
Between the forked foot of the set-lever is a stop-block e, which is adapted to come in- The setbar F has near its pivoted contact with any of the shoulders or stops f of the set-bar F. Now, by freeing the pawl end of the bar F and moving it up or down 011 the rack G the shoulders or stops of said barF are thrown severally into the path of the stop-block e of the set-lever. For example, if a one-inch board is to be made, the bar F is raised on its pivotal center until its pawl f engages the uppermost hole g of the rack G,
and in this position the first shoulder or stop of bar F is thrown into the path of the stopblock 6 of the lever E, thereby limiting the movement of the lever. If a sixteenth is to be added, the pawl end of the set-bar F is dropped down to the second hole of the rack G, so that the second shoulder or stop of the bar is thrown into the path of the stop-block e of the lever E, its first shoulder or stop being dropped low enough to allow said stop-block to pass it. Therefore thelever can move a farther distance, so as to set the knees up a sixteenth more, and so on throughout the series, the bar F moving down on its pivotal center,
lowering all the preceding shoulders or stops and bringing the proper one into the path of the stop-block, this movement being determined by the engagement of the handle end of the bar with the fixed rack G, the holes of which are properly separated and graduated to correspond with the shoulders or stops of said bar.
Pivoted upon a bolt passing through the .lever E is an approximately U-shaped stoppiece H, having its hub formed with notches which are engaged by a spring 71, the said piece carrying also at its free end a screw and adjusting-nut, as shown. The piece H is thrown into use by dropping its end down, so that it will come in contact with the shoulders or stops of the set-bar F, thus limiting the movement of the lever E.
I is the fixed limiting-stop for defining the back limit of the lever.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In saw-mill set-works, and in combination with the vibrating setlever, the pivoted swinging set-bar having a series of shoulders or stops, at fixed rack for limiting and defining the movement of the set-bar, and a stop on the set lever for coming in contact with any of the shoulders or stops of the setbar, according to the position of said bar, substantially as described.
2. In saw-mill set-works, and in combination with the vibrating set-lever, the pivoted swinging set-bar having the series of shoulders or stops, the fixed rack having a series of holes corresponding with the shoulders or stops of the set-bar, a pawl on the end of the set-bar adapted to engage the holes of the fixed rack, and a stop on the set-lever for coming in contact with any of the shoulders or stops of the set-bar, according to the position of said bar, substantially as described.
3. In saw-mill set-works, and in combination with the set-lever having a forked or divided lower portion, the pivoted swinging settion of the lever for coming in contact with any of the shoulders or stops of the set-bar, according to its position, substantially as described.
4. In saw-mill set works, and in combination with the vibrating set-lever having a stop-block, the pivoted swinging set-bar having a series of shoulders or stops with which the stop-block of the lever is adapted to come in contact, the fixed rack for engaging the end of the set-bar and limiting and defining its movement, and the pivoted swinging stoppiece on the lever adaptedto be thrown down to come in contact with the shoulders 01' stops of the set-bar to provide for the saw-kerf, substantially as described.
In witness whereof I have hereunto set my hand.
FREDERICK W. COOK.
